摘  要:
Motor stator faults mainly divides into three categories,namely, grounding, imbalanced three phase dc resistance, and friction. According to motor wiring diagram, megohmmeter, DC resistance tester along with the check process of the stator, lead riser insulating method, metallographic test,was applied to find out the fault point accurately and determine the cause of thefaults, so as to timely repair motor and improve existing processes.
